The specific embodiment
Embodiment 1
The integral structure of the elevator of present embodiment is described according to Fig. 1.Traction rope 3 is wound onto on the rope sheave 4 that rotates by towing machine 6, and traction rope 3 will be connected with counterweight 2 by the car 1 of lifting moving in hoistway.When moving usually, towing machine 6 makes rope sheave 4 rotations according to the instruction from elevator control gear 5.Utilization results from the friction force between rope sheave 4 and the traction rope 3, and traction rope 3 is moved, and the car 1 and the counterweight 2 that are connected with this traction rope 3 are advanced.
In brake gear, brake wheel 7 relies on the elastomeric application of force that is made of retarding spring to be fixed on the rope sheave 4 and rotation, and brake shoe brake cheek is pressed against on the brake wheel 7 with ferrodo 8,9.Therefore, produce friction force between brake wheel 7 and brake shoe brake cheek are with ferrodo 8,9, brake shoe brake cheek is braked with ferrodo 8,9 pairs of brake wheels 7.With this braking interlock, towing machine 6 and rope sheave 4 also are braked, and car 1 and counterweight 2 are braked.
When advancing usually, utilize electromagnetic force to make brake shoe brake cheek leave brake wheel 7 with ferrodo 8,9, make not apply braking force with ferrodo 8,9 to brake wheel 7 from brake shoe brake cheek.
On the other hand, be at elevator under the situation of urgent halted state, it is must state out of service that arrester control device 16 (i) obtains expression from the elevator control gear 5 of the operation of administering elevator, and for car 1 is promptly stopped, the instruction (hereinafter referred to as urgent halt instruction) that should brake brake wheel 7, (ii) from by towing machine coder 11, governor 14, or the car travel information collector unit that constitutes such as position transduser, obtain the position of car 1, the speed of car 1, the information of the travel condition of the cars such as quality 1 of car 1 (hereinafter referred to as travel condition information), according to these information to brake coil 12,13 apply voltage, adjust brake shoe brake cheek ferrodo 8,9 by the power that is pressed on the brake wheel 7.In addition, the situation that arrester control device 16 directly makes car 1 slowly stop to be described herein, but the present application is not limited thereto, also has by counterweight 2 is slowly stopped the situation that car 1 is slowly stopped.In this case, by the counterweight travel information collector unit of car travel information collector unit or replacement car travel information collector unit, calculate the deceleration/decel of counterweight 2, make the deceleration/decel of counterweight 2 follow desired deceleration.
Terminal part in hoistway, the downward running of corresponding car 1 is provided with cage side energy disperser 15a (being counterweight side buffer 15b) when upwards turning round.Under the situation of failing to stop after car 1 is by terminal floor stop, car 1 contacts with cage side energy disperser 15a (being counterweight side buffer 15b when upwards turning round) and the bump when clashing into obtains buffering, can avoid the bump with terminal part thus.In addition, the following describes car 1 and advance downwards, car 1 and cage side energy disperser 15a bump, the situation that car 1 stops, but the invention is not restricted to this, also exist car 1 upwards to advance, counterweight 2 and counterweight side buffer 15b bump, the situation that counterweight stops.
Here, the function of energy disperser 15 is when car 1 enters terminal floor, contacts with car 1 before car 1 arrives terminal part, car 1 is stopped and not bringing the device of strong bump.But, at car 1 with the big speed beyond the anticipation during with energy disperser 15 bumps, in order to ensure car 1 being stopped at contact with energy disperser 15 part to arrive safety in this limited distance of terminal part, the bump increase that car 1 is subjected to.Therefore, energy disperser 15 has bump in the time of will clashing into according to function to be alleviated at specified value with interior predefined speed (hereinafter referred to as specified speed), must be with car 1 speed (hereinafter referred to as velocity of impact) during with energy disperser 15 bumps be set at the speed lower than this specified speed.In addition, in the present embodiment, in order further to guarantee safety, be the speed lower than specified speed that self specified speed describes as benchmark.And the bump that the car 1 the when specified speed of energy disperser 15b is considered counterweight 2 with energy disperser 15b bump is subjected to calculates.
Specify the structure of arrester control device 16 according to Fig. 2.Arrester control device 16 obtains (i) urgent halt instruction and (ii) travel condition information, according to these two signals brake coil 12,13 is applied voltage.Arrester control device 16 comprises safe condition judging part 18, control command portion 19, safety relay 20,21.And safe condition judging part 18 comprises judging part 18b and storage part 18c.The time that stores the speed shown in (L2) among for example a plurality of and Fig. 3 (b) in storage part 18c changes suitable speed curve diagram.
Below, the action of the lift appliance of simple declaration present embodiment.Be at elevator under the situation of urgent halted state, (i) urgent halt instruction and (ii) these two signals of travel condition information be delivered to safe condition judging part 18 and the control command portion 19 of arrester control device 16.
Safe condition judging part 18 considers that the speed of cars 1 comes order safety relay 20,21 switching.Namely, safe condition judging part 18 according to obtain from travel condition information promptly stop to begin the time the speed of car 1, select a speed curve diagram in a plurality of speed curve diagrams from be stored in storage part 18c, judged by judging part 18b whether the travel condition of car 1 should slow down.
Specifically, speed curve diagram according to described selection, will be when promptly stopping to begin the actual speed of the speed on the speed curve diagram after the velocity variations and the car 1 that obtains from travel condition information compare, if the speed of actual car 1 is bigger than the speed on the speed curve diagram, safety relay 20,21 is disconnected, and formation can not weaken the state of the braking force of brake shoe brake cheek ferrodo 8,9 pairs of brake wheels 7.On the other hand, if the speed on the actual speed specific rate diagram of curves of the car 1 of travel condition information is little, then make safety relay 20,21 closures, formation can weaken the state of the braking force of brake shoe brake cheek ferrodo 8,9 pairs of brake wheels 7.That is, whether belong to the control relief areas (velocity band that the curve of specific rate diagram of curves is low is the control relief areas) that Fig. 3 (b) records and narrates according to the state of car 1, judge whether to carry out safety relay 20,21 switching.
Specify safe condition judging part 18 according to Fig. 3.In Fig. 3, (a) time of expression braking force changes, and (b) time of expression speed changes, and (c) the locative time changes, and the quantity of state of car 1 is shown respectively.
Usually, elevator device is configured under the situation of car 1 decline operation and loaded weight maximum (least easily under the situation of braking), safety relay is disconnected, force disconnect is to the energising of brake coil, make and to weaken braking force, by utilizing this braking method (forced brake) to slow down, make velocity of impact reach self below the specified speed.Solid line (L1) among Fig. 3 (b) is illustrated under the situation of car 1 decline operation and loaded weight maximum, by making the forced brake action, makes velocity of impact reach the following velocity curve of self specified speed.In addition, as previously described, usually, elevator device is configured to by forced brake and slows down, and makes velocity of impact reach self below the specified speed, so 15 distance is that Distance Remaining is bigger than the area A Fig. 3 (b) from car 1 to energy disperser.
When judging whether to carry out safety relay 20,21 switching, the speed of car 1 is in control relief areas among Fig. 3 (b) as condition, make the state that can weaken braking force that is in.For example, when car 1 on border that (i) point is in the control relief areas when namely controlling the state on relief areas border (L2), if strengthen braking to drg, then become (L3) such velocity curve.That is, when control relief areas border (L2) is illustrated in car 1 and is positioned on this line, can make the velocity of impact of car 1 become the speed curve diagram of the speed lower than self specified speed by forced brake.
Control relief areas border (L2) utilizes following method to calculate.At first, the computation speed curve is solid line (L1), the velocity variations under the loaded weight that car 1 slows down least easily that solid line (L1) expression is calculated according to following formula (1).Generate according to the following steps then.
(A) with solid line (L1) similarly, with dotted line (L2) draw from the state of braking least easily suitably (amount of certain fixed value) change loaded weight and speed change curves when being changed to the state of braking easily (this state is made as current state).
(B) under current state, slow down the speed change curves (curve corresponding with (L3)) when changing of each point from dotted line (L2) of drawing.
(C) if line (B) all is than the low speed of solid line (L1), then (L2) is made as the boundary line of controllable areas.
(D) if line (B) is not all than the low speed of solid line (L1), then further suitably reduces loaded weight (fixed value of narrating previously that sets), and carry out the operation of (A).

In formula (1), the full conversion inertial mass of elevator is made as m, the braking force of drg is made as F (t), the acceleration force that the weight difference because of car 1 and counterweight 2 is formed is made as F
2And, the speed v of car 1
0Speed when expression promptly stops to begin, t is promptly stopping to begin as the benchmark moment 0 constantly.In addition, utilize the time variation of the speed of solid line (L3) expression also can calculate by the constant definition that partly changes formula (1).In this calculates, the speed v of car 1
0Be made as the speed of the at a point that is positioned at solid line (L1) below, moment t is made as the moment that this at a point moment corresponding is defined as the benchmark moment 0.
Speed at car 1 belongs under the situation of controlling relief areas, weaken the braking force at brake wheel 7, this is because when controlling in controlling relief areas, is in the loading condition than the easier braking of loading condition that is defined as controlling relief areas border (L2).Therefore, suppose to surpass under the situation on control relief areas border (L2) at car 1, in the velocity variations of slowing down by forced brake, the velocity variations of slowing down is solid line (L3) least easily.Because control relief areas border (L2) is definite, solid line (L3) at any time can be than the speed height of solid line (L1), so slow down by forced brake exceeding under the situation of controlling relief areas, thus under the state that car 1 slows down least easily, can slow down as early as possible than the situation of carrying out forced brake from beginning of promptly stopping, and velocity variations afterwards can not surpass solid line (L1).
In addition, in the present embodiment, be velocity curve that solid line (L1) is made as the speed change curves of slowing down by forced brake when being in the state of braking least easily, be illustrated, but the invention is not restricted to this.That is, also can be when car 1 is in least the state of braking easily, car 1 can be in Distance Remaining speed when promptly stopping to begin decelerate to the curve of the velocity variations of self specified speed.Namely, when car 1 is in the state of braking least easily, decelerating to the needed distance of self specified speed with speed when promptly stopping to begin compares, exist under the situation of surplus at Distance Remaining (being collected the information of Distance Remaining by car travel information collector unit), also be set at the velocity curve I ' higher than the velocity curve of the solid line (L1) among Fig. 3 (b) (recording and narrating in Fig. 3 (b ')) sometimes.In this case, can get the big area A of specific floor area A '.That is, can make car 1 carry out milder stopping.
In addition, in the present embodiment, illustrated with the speed of car 1 be stored in storage part 18c in speed curve diagram on corresponding speed compare, but the invention is not restricted to this.That is, also can be in arrester control device 16, according to the state formation speed diagram of curves of the car 1 of reality, and speed and the speed curve diagram of car 1 compared.
In addition, in the present embodiment, also there is situation shown in Figure 4, that is, considers than the low zone of regional upper limit speed that under the situation of forced deceleration, can not accelerate to self specified speed, formation speed diagram of curves.Under and the situation that is being difficult for having been undertaken slowing down by forced brake under the state of braking littler than self specified speed at regional upper limit speed, be defined as can not reaching the speed of self specified speed.For example, under the state that is difficult for braking, the velocity curve (L4) when (ii) surpassing the border can not surpass specified speed.The zone upper limit speed can be defined as v according to following formula

Wherein, each variable and constant are that benchmark defines with car 1, and the full conversion inertial mass of elevator is made as m, and the braking force of drg is made as F (t), and the maximum acceleration force when being the weight difference of car 1 and counterweight 2 maximum is made as F

Embodiment 2
In embodiment 1, the speed according to car 1 of disclosing judges whether to carry out safety relay 20,21 switching, and the method that opens and closes of order, so that be not easy also velocity of impact can be decelerated to self specified speed under the condition that car 1 is braked.In the present embodiment, by detecting loading condition and the direct of travel of car 1, further relax the state that safety relay 20,21 is opened and closed and allow to relax braking force.By relaxing the state that allows to relax braking force, can reduce the frequency that stops suddenly that causes because of not controlled drg.In addition, the loading condition of car 1 for example utilizes scale device 22 to detect, and the direct of travel of car 1 for example utilizes towing machine coder 11 to detect.
The loading condition of car 1 and direct of travel for the state of easily car 1 being braked under, and car speed is when surpassing the border of control relief areas, (L5) that become Fig. 5 over time of car speed and (L6) shown in velocity curve.Like this, (L5) and (L6) and between the solid line (L1) there is surplus.Therefore, detect loading condition and the direct of travel of car 1, and when distinguishing the state that is in easy braking, can further relax the control relief areas.For example, recognizing it is under the situation of the loading condition of braking easily, as shown in Figure 6, in the control relief areas, adding the region alpha of band grid, can further relax the state that weakens braking force.Suppose that when point was in the border of control relief areas, the expression velocity curve of the variation of this quantity of state relatively was (L7), (L8), remains at below the solid line (L1) at (i '), (ii ').In addition, added that the border under the situation of this mesh region α utilizes the set of following point to determine, namely, when at each constantly as when definite certain bench mark draws speed change curves (i '), (ii '), this line all the time with in the line that changes than solid line (L1) and the low speed of self specified speed, the point of speed maximum.
In addition, in the present embodiment, in order to enlarge the control relief areas, illustrated that speed curve diagram depends on the situation of loaded weight and direct of travel, but the invention is not restricted to this.That is, also can enlarge the control relief areas by considering the side in loaded weight or the direct of travel.
Embodiment 3
In the present embodiment, in safe condition judging part 18, the speed of (i) car 1 with (ii) the deceleration/decel of car 1 is as benchmark, judgement can decelerate to velocity of impact self situation below the specified speed, and order safety relay 20,21 switching.In addition, the deceleration/decel of car 1 obtains from car travel information collector units such as towing machine coder 11, governor 14 or position transdusers.
The speed change curves of slowing down by forced brake when the solid line among Fig. 7 (L1) is illustrated in the situation that is in braking least easily, carry out velocity variations by changing low speed with the speed time than solid line (L1), can make velocity of impact decelerate to self below the specified speed.
In safe condition judging part 18, about whether carrying out the judgement of safety relay 20,21 switching, just allow to relax the control of braking force when only satisfying following condition at the same time, namely, (i) speed of car 1 is in the condition in the control relief areas shown in the oblique line among Fig. 6, and (ii) car 1 is in the condition of deceleration regime.
Here, suppose when elevator is in urgent halted state, to satisfy condition simultaneously (i), (ii).So, safety relay 20,21 closures.In this case, if be in because the Heavy Weight of the weight ratio counterweight 2 of car 1, the weight difference performance of car 1 and counterweight 2 makes the state of the effect that car 1 accelerates downwards, and then brake shoe brake cheek is affirmed with ferrodo 8,9 and brake wheel 7 applied braking force.Because if do not apply braking force, then can not be deceleration regime, will with (ii) contradiction.Therefore, the action that safety relay 20,21 is disconnected and reduce speed now by drg 8,9, do not need to consider that brake shoe brake cheek contacts the idling braking time that does not apply braking force before with brake wheel 7 with ferrodo 8,9.
On the contrary, be in since the weight of car 1 unlike the Heavy Weight of counterweight 2, the performance of the weight difference of car 1 and counterweight 2 makes under the state of the effect that car 1 upwards accelerates, even brake shoe brake cheek does not apply braking force to brake wheel 7 with ferrodo 8,9, also can upwards accelerate, namely slow down with respect to direct of travel.In this case, the situation that exists brake shoe brake cheek not contact with brake wheel 7 with ferrodo 8,9.Therefore, the action that safety relay 20,21 is disconnected and reduce speed now by drg 8,9, in order to suppose the situation of more difficult deceleration, need to consider that brake shoe brake cheek contacts the idling braking time that does not apply braking force before with brake wheel 7 with ferrodo 8,9.
Therefore, carry out under the situation of forced brake in that safety relay 20,21 is disconnected, it is to consider the situation that idling braking time is braked downwards and (ii) do not consider the situation that idling braking time is braked downwards when car 1 does not accelerate when car 1 accelerates at (i) that velocity of impact reaches maximum.
In Fig. 7, with (i), (ii) be benchmark, the dotted line of Yan Shening (L3), (L5) are illustrated under the condition that does not have the unbalanced power that causes from here, do not consider the speed change curves when idling braking time carries out forced brake, solid line (L4), (L6) are illustrated under the condition of the unbalanced masterpiece that causes for the direction that car is accelerated, and do not consider the speed change curves when idling braking time carries out forced brake.When the border of control relief areas is confirmed as the set of following point, can make the control relief areas enlarge β, make the control relief areas reach maximum, described point refers to draw these velocity of impacts might be for the Velocity-time change curve of maximum the time changing as the time of benchmark, the point in the line that these lines of each time change in than the low velocity band of solid line (L1), when reaching maximum as the speed of benchmark.Show an example of concrete steps of determining the boundary line of control relief areas according to said sequence below.
(A) on the Velocity-time plane, with the time 0 be benchmark, the solid line of object (L1) as a comparison draws.
(B) same, on the Velocity-time plane, with the time 0 be benchmark, draw (i), time changing curve (ii).Since 0 suitably speed and the setting-out of increase (amount of certain fixed value) conduct benchmark at this moment, compare the magnitude relationship of each (i), line (ii) and solid line (L1).Its result is (i), (ii) than the boundary point of the maximum speed in the little line of solid line (L1) as this control relief areas constantly.
(C) suitably increase time in (amount of certain fixed value) step (B), generate the boundary point of each control relief areas constantly, the set of getting these points forms the boundary line of control relief areas thus.
In the present embodiment, be the condition judgment of deceleration regime by adding car 1, compare with embodiment 1, embodiment 2, have and can enlarge the control relief areas, relax the effect of the state that can control.
In addition, under the loading condition of braking easily, be suitable for condition (i) in the present embodiment, (ii) the time, can add that the mesh region β shown in Fig. 6 enlarges to the control relief areas.
